Good day! I'm a newbie in C. I'm trying to get an unlimited input from the user using malloc then printing the inputs after the user presses enter. My code works, but there's a warning that I don't know how to fix. Please help me. Thank you.
Here's my code:
I get the warning: passing of argument 2 of 'fgets' makes integer from pointer without a cast
hello sir
since by mentioning a integer pointer and storing the integers
by incrementing the pointer value
then what is the purpose of malloc?
u can decalre it as
in t *p;
several integers can be stored by incrementing the value of p,
hence what is the diffrence between this... (2 Replies)
Hi!
I hope this is the correct forum to post the question even if I'm a newbie...
I am a C-newbie (and really on the edge to be a C-addict ;) ) and have a question.
When should I use malloc?
To state it differently, when should I NOT use malloc?
For instance, if I have an array of... (5 Replies)

Hey Guys
I am trying to implement the malloc function for my OS class and I am having a little trouble with it. I would be really grateful if I could get some hints on this problem.
So I am using a doubly-linked list as my data structure and I have to allocate memory for it (duh...). The... (1 Reply)
Hey Guys
Some of my friends have got together and we are trying to write a basic kernel similar to Linux. I am trying to implement the malloc function in C and I am using a doubly linked list as the primary data structure. I need to allocate memory for this link list (duh...) and I don't feel... (2 Replies)
Why when using realloc, john is reversed 3 times but not the other 2 names ? But if I use malloc, then the 3 names are reversed correctly ? (but then there is a memory leak)
How can I reverse all 3 names without a memory leak ?

Hi i found code in google how to malloc an 2D array and i tried that :
#include<stdio.h>
#include<stdlib.h>
int **A;
int **B;
int main(int argc,char *argv)
{
printf("name of text : %s\n",argv);
//read arrays
int i,j;
int l,m;
int M,n;
FILE *fp;
fp=fopen(argv,"r");

Which one is faster among malloc and new?
My understanding is that since new also has to call constructors after allocating memory it must be slower than malloc.
Am I correct? (1 Reply)

gets
GETS(3) Library Functions Manual GETS(3)NAME
gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(char *s)
char *fgets(char *s, int n, FILE *stream)
DESCRIPTION
Gets reads a string into s from the standard input stream stdin. The string is terminated by a newline character, which is replaced in s
by a null character. Gets returns its argument.
Fgets reads n-1 characters, or up through a newline character, whichever comes first, from the stream into the string s. The last charac-
ter read into s is followed by a null character. Fgets returns its first argument.
SEE ALSO puts(3), getc(3), scanf(3), fread(3), ferror(3).
DIAGNOSTICS
Gets and fgets return the constant pointer NULL upon end of file or error.
BUGS
Gets deletes a newline, fgets keeps it, all in the name of backward compatibility.
Gets is not present in the Minix-vmd C library for reasons that should be obvious. Use fgets instead.
